web ide: security headers (#1063)
* web ide: security headers

includes security headers for content policy and other security related
features.

includes style fixes to hide terminal, debugger, and navigation widget.

* webide: update to latest sdk

* web ide: re-enable open widget, enable telemetry

* even though we know arbitrary commands can be run from the open
widget, it is too useful to disable

* raised issue where opting out of telementry causes critical errors in
the plugin. For now, we are enabling the telemetry by default (even
though it actually doesn't log anything because our network security
does not allow that traffic to go out)

Welcome to the DAML repository!

This repository hosts all code for the DAML smart contract language and SDK, originally created by Digital Asset. DAML is an open-source smart contract language for building future-proof distributed applications on a safe, privacy-aware runtime. The DAML SDK is a set of tools to help you develop applications based on DAML.

Using DAML

To download DAML, follow the installation instructions. Once installed, to try it out, follow the quickstart guide.

If you have questions about how to use DAML or how to build DAML-based solutions, please ask them on StackOverflow using the daml tag.

Contribuing to DAML

We warmly welcome contributions. If you are looking for ideas on how to contribute, please browse our issues. To build and test DAML:

1. Clone this repository

git clone git@github.com:digital-asset/daml.git
cd daml

2. Set up the development dependencies

Our builds require various development dependencies (e.g. Java, Bazel, Python), provided by a tool called dev-env.

Linux and Mac

On Linux and Mac dev-env can be installed with:

  1. Install Nix by running: bash <(curl https://nixos.org/nix/install)
  2. Enter dev-env by running: eval "$(dev-env/bin/dade assist)"

If you don't want to enter dev-env manually each time using eval "$(dev-env/bin/dade assist)", you can also install direnv. This repo already provides a .envrc file, with an option to add more in a .envrc.private file.

Windows

Note that the Windows build is not yet fully functional and is not supported.

On Windows you need to enable long file paths by running the following command in an admin powershell:

Set-ItemProperty -Path 'HKLM:\SYSTEM\CurrentControlSet\Control\FileSystem' -Name LongPathsEnabled -Type DWord -Value 1

Then start dev-env from PowerShell with:

.\dev-env\windows\bin\dadew.ps1 install
.\dev-env\windows\bin\dadew.ps1 sync
.\dev-env\windows\bin\dadew.ps1 enable

In all new PowerShell processes started, you need to repeat the enable step.

3. First build and test

We have a single script to build most targets and run the tests. On Linux and Mac run ./build.sh. On Windows run .\build.ps1. Note that these scripts may take over an hour the first time.

To just build do bazel build //..., and to just test do bazel test //.... To read more about Bazel and how to use it, see the Bazel site.

4. Installing a local copy

On Linux and Mac run da-sdk-head which installs a version of the SDK with version number 0.0.0. Set the version: field in any DAML project to 0.0.0 and it will use the locally installed one.

On Windows:

bazel build //release:sdk-release-tarball
tar -vxf .\bazel-genfiles\release\sdk-release-tarball.tar.gz
cd sdk-*
daml\daml.exe install . --activate

That should tell you what to put in the path, something along the lines of C:\Users\admin\AppData\Roaming\daml\bin. Note that the Windows build is not yet fully functional.

Caching: build speed and disk space considerations

Bazel has a lot of nice properties, but they come at the cost of frequently rebuilding "the world". To make that bearable, we make extensive use of caching. Most artifacts should be cached in our CDN, which is configured in .bazelrc in this project.

However, even then, you may end up spending a lot of time (and bandwidth!) downloading artifacts from the CDN. To alleviate that, by default, our build will create a subfolder .bazel-cache in this project and keep an on-disk cache. This can take about 10GB at the time of writing.

To disable the disk cache, remove the following lines:

build:linux --disk_cache=.bazel-cache
build:darwin --disk_cache=.bazel-cache

from the .bazelrc file.

If you work with multiple copies of this repository, you can point all of them to the same disk cache by overwriting these configs in either a .bazelrc.local file in each copy, or a ~/.bazelrc file in your home directory.
